MIAMI Slovakia's Dominika Cibulkova fought of three match points to claim a 3-6 7-6 (7-5) 6-3 upset win over third seed Agnieszka Radwanska of Poland at a windswept Crandon Park on Wednesday to reach the Sony Open semis.
With both players struggling in cool, blustery conditions, the 10th seeded Cibulkova reached the final four for the first time in eight visits to Miami despite being broken 10 times, committing 51 unforced errors and eight double faults.
The match was certainly not of the same quality the pair showed in their Australian Open semi-final earlier this year, as Cibulkova waited until the fourth game of the second set before managing to hold serve for the first time.
"I have to say I'm really glad, especially about my win today," said Cibulkova, who will move into the top 10 of the world rankings for the first time with the win.
"It wasn't easy at all to play today against Aga with the wind and conditions and I had to stay aggressive all the time even if I missed many shots."
With the wind whipping and swirling around centre court, the game opened with five consecutive breaks before Radwanska held serve to grab a 4-2 lead.
But the set would end the way it began with three more breaks and Radwanska taking a 1-0 lead.
The slew of breaks extended into the second set with three more breaks before Cibulkova held serve for the first time.
Trailing 5-4 in the second set and serving to stay alive, Cibulkova staved off three match points before holding and then breaking Radwanska en route to winning the set in a tiebreak.
"It was so close, the second set," said Radwanska. "But I think, you know, in those matches you have to play good and you have to be lucky.
"I was just playing good and she was both."
Radwanska, with her left knee and right shoulder already heavily taped, called for the trainer at the changeover and had even more plaster applied to right hand.
When play resumed Radwanska quickly found herself down a break and could never regain control, Cibulkova eventually falling onto her back and raising her hands in triumph after watching the Pole's return sail long.
Cibulkova, who took out three-time champion Venus Williams in the fourth round, will now await the winner between world number two Li Na and former world number one Caroline Wozniacki, who play later on Wednesday.
